augment, increase, multiply, raise
殖 centers on growth in quantity or scale: augmenting, increasing, multiplying, or raising something to a larger amount.
殖 combines 歹 (originally a pictograph of a broken bone, often associated with death or harm) with 直, which likely contributes the sound. The compound originally referred to the proliferation of harmful things, later broadening to general increase or multiplication.
The left side 歹 suggests something spreading (like decay), and the right side 直 (straight) hints at direct, unchecked growth. Picture a fast-spreading vine that multiplies and raises its shoots straight up.
For ショク, imagine a shock of new growth: shock -> ショク, as plants suddenly augment and multiply after rain.
